PRESSURE-CONTROLLED GAS-IGNITER.

Specification of Letters Patent.

Application filed July 11, 1908.

Patented Dec. 22, 1908.

Serial No. 443,018.

To all whom it may concern:

Be it known that I, EDUARD ZIoxwoL'rF, a mechanic, a subject. of the Emperor of Germany, residing at Siegen, Westphalia, in the German Empire, have invented a certain new and useful Improvement in Pressure-Controlled Gas-Igniters, of which the following is a specification.

This invention relates to remote-controlled gas-burners of the type wherein the alternate opening and closing of the gas-orifices for the principal flame. and igniting flame is effected by means of impulses or waves of gas-pressure transmitted through the gasconduit to act on a membrane, bell-jar or the like connected to a valve-lever.

The present invention consists in so constructing the mechanism that a valve-lever with arms of unequal lengths forcibly thrusts the valve against the valveseat of the principal burner orifice, so that a tight closure is obtained even if impurities are deposited on the said valve and seat.

A construction embodying the invention is shown in the annexed drawings, in which Figure 1 is a vertical section of the mechanism, showing the conduit leading to the main burner-orifice closed. Fi 2 is a horizontal section on line 2-2 of Fig. 1, and Fig. 3 a front view partly in section. Figs. 4 to 7 illustrate difi'erent positions of parts of the mechanism.

In the construction illustrated a rod or in the casing b is connected to a bell-jar (l which is partly immersed in liquid in an annular chamber 6 The said rod is connected to a lever g pivoted at i, and from the free end of the said lever a dog is is suspended. The dog It is adapted to engage a ratchet-wheel m fixed to a shaft n, to which is also fixed a cam 0. The Weighted valve-lever p pivoted at 1" rests uponthe said cam, and the shorter arm p of the said lever engages the valve-body s. The latter is movable between the orifices of two ducts t and t which lead respectively to the main burner orifice and to the igniting burner orifice. A pawl it engages the ratchet-wheel m to prevent backward rotation thereof.

In Figs. 4 to 7 the dog and ratchet-mechanism g 70 m is shown on the left-hand side and the cam and valve mechanism on the right-hand side. When the dog and ratchet and cam are in the positions shown in Fig. 4

the valve 8 closes the orifice of the conduit 25.

If a Wave of pressure is sent through the 1 gas-main the bell-jar d is lifted and actuates the mechanism a g I: m, theshaft n being rotated through an angle which causes the lever 19 to be lifted by the cam 0. This causes the valve 8 to be lowered on to the orifice of the conduit t leading to the igniting burner, and the igniting flame is extinguished; the conduit 25 having been meanwhile opened by the lowering of the valve. The next actuation of the mechanism causes the lever 79 to slide off the cam 0 (Fig. 6) and to thrust the valve 8 with a suitable amount of force against the orifice of the conduit t. By this means the valve is thrust firmly against its seat and displaces impurities deposited thereon. The next actuation of the mechanism causes the conduit t to be reopened and the conduit t to be closed (Fig. 7). Preferably the cam-surfaces are made of such length that several actuations of the mechanism must take place before the lever 79 slides from the cam and closes the conduit t. In a street-lighting system the igniters may then be so distributed that a single wave of pressure causes all the lamps to be lighted, and that the next wave causes alternate lamps to be extinguished, the remaining lamps being extinguished by the third wave.

To allow of actuating the mechanism by hand a lever w is fulcrumed at 'v on the cover I) of the casing. This lever engages the rod a and has a chain, cord or rod g connected to it, by means of which it can be actuated for lifting the rod a. This arrangement enables individual lamps to be separately lighted and extinguished.

What I claim as my invention and desire to secure by Letters Patent of the United States is I. In a remote controlled gas igniter, the combination with the illuminating and igniting burners of two gas ducts having orifices opposed to one another, a valve between said orifices, a lever having a short arm cooperating with said valve and having a long weighted arm, a cam for cooperating with said weighted arm and means for rotating the cam adapted to be operated by variations of gas pressure.

2. In a remote controlled gas igniter, the combination with the illuminating and igniting burners of two gas ducts having orifices opposed to one another, a valve between said orifices, a lever having a short arm cooper ating with said valve and havinga long weighted arm, a cam of determined length for cooperating With said weighted arm, and

means for imparting partial rotations to said cam by variations of gas pressure, the length of the cam being proportioned to operate the lever upon a predetermined plurality of impulses. 1

3. In a remote controlled gas igniter, the combination With the illuminating and igniting burners of two gas ducts having orifices opposed to one another, a valve between said orifices, a lever having a short arm cooperating With said valve and having a long Weighted arm, a cam for cooperating With saidzweighted arm and means for rotating the cam adapted to be operated by variations of gas pressure, and hand operatable mechanism tor operating said cam rotating mechanism alternatively by hand. 7

In Witness whereof I have signed this specification in the presence of two witnesses.
